Step-by-step explanation:
Question B:
Number of boys = 6
Number of girls = 4
Number of people in committee = 3
Number of ways of selecting committee with atleast 2 girls :
We either have :
(2 girls 1 boy) or (3girls 0 boy)
(4C2 * 6C1) + (4C3 * 6C0)
nCr = n! ÷ (n-r)!r!
4C2 = 4! ÷ 2!2! = 6
6C1 = 6! ÷ 5!1! = 6
4C3 = 4! ÷ 1!3! = 4
6C0 = 6! ÷ 6!0! = 1
(6 * 6) + (4 * 1)
36 + 4
= 40 ways

how to divide m96 in the ratio 5:7
Hey! I dont know if this will help though
To solve this question, you must first add together the two halves of the ratio i.e. 4 + 2 = 6. Then you need to divide the total amount using that number i.e. 600/6 = 100. To work out how much each person gets, you then multiply their share by 100.

ITS CORRECT CUZ SAME ANGLE, AND TWO OF THE SAME SIDES
Plz answer I’ll mark brainliest . In each of the circles below, four angles are formed by the intersection of two secant lines.
The measures of two intercepted arcs and one angle are shown for the first three circles.
Which equation could be solved to find an expression that represents the measure of qs in
degrees?
9514 1404 393
Answer:
B
Step-by-step explanation:
The angle where the chords cross is half the sum of the intercepted arcs. The expression below says that. It is the 2nd choice.
Find the equation of the line through point (1,−5) and perpendicular to y=1/8x+2. Use a forward slash (i.e. "/") for fractions (e.g. 1/2 for 12).
Answer:
[tex]y = -8x + 3[/tex]
Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:
[tex]y = mx + b[/tex]
In which m is the slope and b is the y-intercept.
Perpendicular lines:
When two lines are perpendicular, the multiplication of their slopes is -1.
Perpendicular to y=1/8x+2
This line has slope [tex]\frac{1}{8}[/tex]
So, for the line we want to find the equation, we have that:
[tex]\frac{m}{8} = -1[/tex]
[tex]m = -8[/tex]
So
[tex]y = -8x + b[/tex]
Find the equation of the line through point (1,−5)
This means that when [tex]x = 1, y = -5[/tex]. We use this to find b. So:
[tex]y = -8x + b[/tex]
[tex]-5 = -8 + b[/tex]
[tex]b = 3[/tex]
The equation of the line is:
[tex]y = -8x + 3[/tex]

A ramp rises 4 ft. and makes a 20 degree with the ground. How
long is the ramp?
Answer:
P = 1.36 feet
Step-by-step explanation:
Given that,
Height of ramp, H = 4 ft
The ramp makes an angle of 20 degree with the ground.
We need to find the length of the ramp.
The height of the ramp is the hypotenuse and the length of the ramp is perpendicular of the right angled triangle. Using trigonometry to find the length of the ramp i.e.
[tex]\sin\theta=\dfrac{P}{H}\\\\P=H\sin\theta\\\\P=4\times \sin(20)\\\\P=1.36\ ft[/tex]
So, the length of the ramp is equal to 1.36 feet.

On a standardized exam, the scores are normally distributed with a mean of 135 and a
standard deviation of 20. Find the Z-score of a person who scored 115 on the exam.
Answer:
-1
Step-by-step explanation:
mean, mu = 135.
Standard deviation = 20
X = 115
use the z score formula : [tex]z = \frac{x-mu}{standard deviation}[/tex]
to get (115-135)/20 = -1

Answer:
x = 70
Step-by-step explanation:
The angle between the tangents is the supplement of the intercepted arc:
x° = 180° -110°
x° = 70°
__
Alternate solution
The exterior angle x° is half the difference of the intercepted arcs. Long arc ACB is 360° -110° = 250°, so we have ...
x° = (250° -110°)/2 = 140°/2
x° = 70°
__
If you work this alternate solution generically, you find it is the same as the first solution.
x = ((360 -AB) -AB)/2 = (360 -2AB)/2 = 180 -AB

Need help ASAP PLEASE!!
Answer:
x=4
Step-by-step explanation:
-3(4x+3)
you need to break open the paranthesis
-3 times 4x equals to -12x. -3 times 3 equals to -9. That means that this expression is equal to -12x-9.
4(6x+1)
you need to break open the paranthesis
4 times 6x equals to 24x. 4 times 1 equals to 4. That means that this expression is equal to 24x+4.
-12x-9+24x+4=43
move all variables to the left side and numbers to the right side
-12x+24x=43-4+9
12x=48
x=4
Two lines extend from point S to create a right angle. The vertical line extends from point S through point R. The horizontal line extends right from point S through point T. A third line extends right and up from point S through point U.
Which is the endpoint of a ray?
point R
point S
point T
point U
Answer:
point s
Step-by-step explanation:
the other three lines continue infinitely
The endpoint of a ray based on the information given is B. point S
What is an endpoint?It should be noted that the endpoint simply refers to the straight lines that connect two points.
From the information and diagram given, a line extends right and up from point S through point U.
Therefore, endpoint of a ray based on the information given is point S
